1 transistor regenerative receiver. This project was designed and built by Charles Kitchin. Regenerative receivers (in German literature also called " Audion ") are a very clever way to build receivers with a very small number of active components. 6 to 25 MHz, which includes Nov 23, 2016 · 1966 One Transistor Regenerative Receiver Fifty years ago, the “Beginner’s Corner” of the November 1966 issue of Electronics Illustrated carried three circuits for basic radio receivers. Well, that's what I ended up building, an Armstrong type regenerative radio, but unlike the regenerative radio I built in 1958, this time I decided to use 1970s technology instead of 1920s technology and use a Field Effect Transistor (FET) in place of the venerable old 1H4 thermionic tube that I used as the detector of that early project. We have chosen to build this receiver with bipolar transistors which have the advantage of being relatively solid, inexpensive and easy to control with an ohmmeter. As with the previous circuit, this design uses a bipolar RF stage, a J FET detector and an IC audio stage. Please refer the following circuit diagrams below and video clip links, to see these receivers working before proceeding with the construction details. Feb 15, 2024 · The receiver I've put together is based on the iconic Chinese radio "636" design from 1963. Apr 21, 2020 · My other hobby is designing and building simple, one transistor regen receivers, most of which tune the AM broadcast band, although I have built a couple covering the lower portion of the HF broadcast bands as well, just for a challenge. 75. 3pnok8 vl0b al 66tb 0mly puh 5vc 88z0 ocr xa
